LUBRICATOR` SPECIFICATION forming part of Letters Patent No. 667,148. dated January 29, 1901. Application tiled July 3, 1900. Serial No. 22,400. (No model.)

To ttZZ whom it may concern:

Beit known that we, WILLIAM L. GARRELS, a resident of the city of St. Louis, and CLIN- TON KIMBALL, a resident of the city of Kirkwood, St. Louis county, State of Missouri, citizens of the United States, have invented certain new and useful Improvements in Lubricators,of which thefollowingis a specification.

Our invention relates to lubricators for steam-engine cylinders, and has for its principal object to provide for the lubrication of the cylinders and Valves of steam-engines when it is desirable to place the parts of the lubricator substantially below the connection between the lubricator and the steam-pipe or throttle-Valve.

Other objects are convenience of manipulation, compactness of construction, and theimprovement of the construction in general.

It also consists in the arrangements and combinations of parts hereinafter described and claimed.

In the accompanying drawings, which form part of this specification, and wherein like symbols refer to like parts wherever they occur, Figure 1 is 'a vertical sectional view of our device. Fig. 2 is a vertical sectional view oa modification wherein the outer member of the swivel is formed on the reversible portion of the device. Fig. 3 is a vertical view, partly sectional, showing the reservoir made of glass and a passage-way through the piston. Fig. 4 is a cross-section of the device illustrated in Fig. 3, and Fig. 5 is a vertical section of a modified form of our device.

The oil-reservoir of our device consists of a hollow cylinder l, containing a piston or plunger 2. The end of the cylinder 1 which is the lower end when the device is in its working position is closed by alling-plug 3. A passage-way 4 connects the said lower end of the cylinder 1 through a valve 5 for regulating the feed of the oil to a passage-way 6. In order to indicate the condition of the feed, one or more bulls-eyes 7 or a glass tube are inserted in said passage-way 6. A passageway 8, which opens into the end of the cylinder opposite the filling-plug, and the passageway 6, both extend upwardly when the device is in its workingposition into a substantially horizontallyarranged cylindrical or conical cock or swivel-stem 9. The passageway 6 and the passage-Way 8 both open into a passage-way 10, formed in the casing 11 of the swivel-stem. Said passage-way communicates with the steam-pipe l2 or with the throttle-valve of the engine the Valves and cylinders of which are to be lubricated. In order to insure easy working of the swivel 9 and prevention of leakage, it is preferable, especially for a high steam-pressure, to provide each end of the swivel with packing 13. Said packing at each end is made independently adjustable with respect to the packing at the other end by means of the nuts 14, which screw onto the swivel-stem 9. When the swivel is turned half a turn, the passageway 8 registers with the drain 15, while the passage-way 6 is closed. It is preferable to provide said drain 15 with a valve 16 for controlling the drain and also, especially when high steam-pressure is used, to prevent leakage from the passage-way 10 into the surrounding atmosphere.

The operation of filling our device with oil and of feeding the oil for use is as follows: When the device'is in its working position, condensed steam fills the part of the cylinder 1 above the piston 2 and also fills the passageway 8, the passage-way 6, and the passageway 10 up to the place of connection with the steam-pipe 12 or with the throttle-valve. To till the lubricator, it is turned on the swivelstem into its inverted position. In this position communication with the steam-pipeis cut off and the passage-way 6 is closed. The water in said passage-way 6 consequently remains in it. .The tillerplug 3 is then removed. The water in the cylinder 1 is now drained off by opening the valve 16. This causes the pistou 2 to sink on account of its weight to what in the working position ot the device is the top of the cylinder 1. The oilreservoir 1 is now iilled with oil and the fillerplug 3 is replaced. When the lubricator is turned into its lower position, it is ready to feed, the adjustment of the valve 5 not having been changed and the water in the passage-ways 6 and 10 not having been drained during the operation of iilling. The pressure required to force the lubricant through the valve 5, which is preferably a needle-Valve,

IOO

is obtained from the weight of the piston 2 itself, the means for exerting pressure on the oil being thus entirely inside of the cylinder. The drops of oil after passing the valve 5 fioat up through the passage-ways 6 and 10 and then flow into the steam-pipe or throttlevalve. Any leakage of oil past the piston 2 would have the effect merely of feeding to the engine a slightly-additional amount of lubricant, which would not be visible at the said sight-glass. As the passage-ways G and S lead to the same source of steam-pressure and the piston is consequently subjected. to the same steam-pressure on both sides, it is obvious that the pressure on both sides due to the steam is balanced. Obviously, therefore, any other arrangement of passage-ways which will result in balancingthesteam-pressure on the two sides of the piston is the equivalent of the two passage-ways 6 and 8 and may be substituted therefor for equalizing the pressure in the ends of the cylinderas, for instance, an opening directly through or past the piston, such as a groove cut into the piston or cylinder wall. Fig. 3 shows such a modification. In this modification the passage-ways 4 and 6 are located in the piston 2 itself. So, also, the valve 5, if used, should be mounted in said piston; but obviously the valve may be omitted entirely. In this modification the sight-glass 17 forms the walls of the cylinderl, thus showing not only the condition of the feed, but also the quantity of oil in the reservoir. A sightglass could obviously be placed in eitherthe passage-way 8 or the passage-way 10.

Our device is especially adapted for use in connection with steam -automobiles, as no part of it need be above the place of connection with the steam-pipe or throttle-valve. Then the vehicle is stopped, the device may be turned into its inverted position and the feed of the oil thereby stopped. If the driver should forget to turn it back upon again starting, it will turn back automatically on account of its weight and of the vibration of the vehicle.

Divers modifications may be made in the construction above described without depart.- ing from our invention. For instance, the passage-ways 6 and S may enter the casing through the end of the swivel-stem. The body portion or stem of the lubricator may be made to form the female part of the swivel, as shown in Fig. 2. So, too, the passageways G and S may be made to both register with a drain 15, as indicated by the dotted line in Fig. 2. ln case the device to be lubricated is exposed to atmospheric pressure the end of the cylinder may be left open to the atmosphere, so as to equalize the pressure on the piston therein in opposite directions. Ordinary journals, axles, and slides are illustrations of such a case. It is usual to feed the oil or grease to such devices downwardly instead of upwardly, and our invention contemplates feeding the lubricant in either dieem-is rection. When it is desired to use a perforated piston or weight for lubricating such bearings, a groove 18 may be cut in its side from the top nearly to the bottom of said piston and in position to register with a port or passage-way 19, connected to the bearing to be lubricated, as will be obvious from an i11- spection of Fig. 5 of the drawings.

Our invention admits of various other modifications, and we do not wish to limit ourselves to the above details of construction.
